Since 1 g fat contains 9 calories, dividing 600 by 9 results in 600 calories containing 67 grams of fat.

Extended data:

There are three kinds of calories in food: protein's calories are the basic nutrients to strengthen muscles, mainly from meat, dairy products and eggs, with 4 calories per gram; Carbohydrate calories are the main energy source of human body under normal circumstances, which are contained in rice, flour, noodles, bread, cereals, vegetables and fruits, and each gram of calories is also 4 calories; Fat contains 9 calories per gram, which is found in both oil and cream.

The ideal calorie ratio of each meal is probably: carbohydrate 65%, fat 20%, protein 15%.

Don't deliberately control fat intake. Excessive dieting will do harm to the stomach and digestive system. Some doctors pointed out that the control of energy intake should be gradual, so as to ensure that the human body can adapt slowly, and the energy intake per day is generally not less than 800 calories. Otherwise, the human body will make up for the lack of energy intake by reducing the body function, which usually leads to dizziness and fatigue, and the reduction of basal metabolic consumption will also affect the efficiency of weight loss.
